Chapter 20, Problem 20.51SP

Interpretation Introduction

Interpretation:

The stronger reducing agent from given set of metal ions namely $T{i}^{2+}$ and ${\text{Ni}}^{\text{2+}}$ should be identified.

Concept Introduction:

Reduction: If electrons are gained to a species during a chemical reaction. The species which gets electrons are said to be reduced.

Oxidation: If electrons are moved from a species during a chemical reaction. The species whose electrons are removed is said to be oxidized.

Reducing agent: The chemical substance is considered as reducing agent if it is capable of donating more electrons which reduces the other substance and getting oxidized by itself during the process.

Effective nuclear charge: It is the charge experienced by the valence electrons from the nucleus. Effective nuclear charge increases across a period because increasing nuclear charge with no accompanying increase in shielding effect.
